Abstract: 956,169. Belt fasteners. HAYDEN-NILOS Ltd. Jan. 9, 1963 [Jan. 25, 1962], No. 2764/62. Heading F2Q. In a fastener for a conveyer belt, wherein abutting belt ends 1A, 1B to be joined are sandwiched between bridging plates 3, pointed limbs 5 of each of U-shaped wire staples 6 pass through a pair of holes 4 spaced lengthwise of the belt in one plate, the belt thickness, and a registering pair of holes in the other plate, and are bent over the outer surface of said other plate away from the abutting belt edges. The width of the plates is restricted to permit the belt to trough. In Figs. 1, 3, the plates are contiguous across the belt width and are corrugated to present three external parallel grooves receiving the staple bases and bent over points and corresponding inner ribs pressing into the belt faces. In Fig. 6 (not shown), wherein the inner plates have three pairs of holes in each end, outer plates of stout wire flattened and grooved at each end receive only one staple at each end and may be contiguous at their ends across the belt width or lie clear of each other. The staples may be initially detached and their limbs may be a force fit in the plate through which they are first passed, or initially secured to one plate, as by spot-welding at their bases or being force-fitted into the holes of that plate. As in Specification 955,905, the staple limb points may be bent over by recesses in a pointreceiving anvil which may be movable lengthwise of the belt for compression of the bent points. Should the staple limb points overlap the adjacent plate end they may be turned into the belt material. Preferably, after bending over, the points should be further pressed to compress the plates tightly to the belt material.

Title: Improved electric measuring apparatus of the bridge type
Inventor: WALKER EDWARD ALEXANDER
IPC: G01R17/00
Filed: 1951-02-06
Abstract: 690,890. Bridge circuits. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Feb. 5, 1952 [Feb. 6, 1951], No. 2920/51. Class 37. A coupling circuit for connecting the output of a measuring bridge to a detector through an output transformer comprises a frequency mixer connected between the bridge and the output transformer, and a local oscillator adapted to supply to the mixer current at such frequency that the frequency of the current in the output transformer is within a range having a substantially smaller ratio of maximum to minimum value than the frequency range in the bridge. The local oscillator 4 feeds the mixer 3 through an input transformer 5, the resultant beat frequency being taken from the mixer through an output transformer 6. If the bridge is set for measuring at a frequency consecutively varying in the range of 10- 500 kc/s. the local oscillator has a range of 1010-1600 kc/s. The adjusting members are so ganged that the output of the local oscillator changes in step with the measured frequency giving a constant beat frequency of 1000 kc./sec. Fig. 2 shows a suitable arrangement of the mixer stage using a crystal rectifier. Within an electrostatic screen 8 there is arranged the secondary winding 9 of the local oscillator input transformer 5 which has connected across it a tuning capacitor 10 and a damping resistor 11 which gives a wide frequency band response. Outside the screen is the primary winding 12 with a partial screen 13 for the winding. At the other side of the chamber formed by the main screen 8 is the primary winding 14 of the output transformer 6 for the beat frequency current, with a tuning capacitor 15 connected across it. Outside the screen is the transformer secondary winding 16 which has a partial screen 17. The secondary winding 9 and primary winding 14 are connected in series with a crystal rectifier 18 and a resistor 19, which is connected across the bridge output terminals 1, 2. This serves as a load for the rectifier 18 and a path for the D.C. component.

A method of coating the interior of a pipe comprises pulling through the pipe being coated a flexible pipe of smaller bore conveying a liquid or plastic coating medium under pressure, and discharging same by spraying it from one or more nozzles, or nozzle having a plurality of discharge orifices, the resultant spray being directed, e.g. by a rotating deflecting device, on to the interior of the pipe being coated. The flexible pipe adjacent the nozzle or nozzles is supported by guide means taking support from the wall of the pipe being coated. The deflecting device is rotated by the impingement thereagainst of the coating medium or by a separate driving means comprising a compressed air motor, the air under pressure for driving being ducted through the pipe being coated by a second flexible pipe. A suitable apparatus comprises a body 10 rotatable about a central axis, said body 10 comprising a circular base plate 11 and upstanding steel bars 13 spaced around the periphery of said base plate, and carrying a container 14 for the coating medium, and means for forcing the medium from the container 14 through the flexible pipe 15 to nozzles (not shown), said forcing means comprising a pump 23 powered by compressed air supplied by compressor 17 driven by internal combustion engine 16, or alternatively bottle or bottles 34 of compressed nitrogen or other gas, the pressure in bottle 34 being controlled by reducing valve 36. A filter unit 38 may be present between container 33 and the nozzles. In use, the flexible pipe 15 or 37 carrying the nozzles is inserted into the pipe to be coated and as the flexible pipe is withdrawn therefrom by rotating the frame member 10 or 30 around which the flexible pipe winds, the interior of the pipe is coated.

Abstract: 2 : 7-Dinitroacridone of the formula <FORM:0602331/IV(b)/1> is prepared by treating 2-nitroacridone with a nitrating agent in a solvent which is substantially unaffected by the nitrating agent, e.g. sulphuric acid or a mixture thereof with a normally liquid fatty acid.  The nitrating agent may be nitric acid, a mixture of nitric and sulphuric acids, or a mixture of a metallic nitrate, e.g. an alkali metal nitrate, and sulphuric acid or an acyl nitrate, e.g. acetyl nitrate.  The rate of addition of the nitrating agent is preferably controlled so that the temperature of the reaction mixture does not exceed 30 DEG  C. 2 : 7-Dinitroacridone, prepared as above, may be reduced to 2 : 7-diaminoacridone by any one of the reagents known to reduce an aromatic nitro substituent to an amino substituent.  2 : 7-Diaminoacridone, prepared as above, may be reduced with sodium amalgam in neutral or slightly alkaline solution to yield 2 : 7-diaminoacridone which is oxidized to 2 : 7-diaminoacridine with oxygen in the presence of a ferric salt and converted to 2 : 7-diaminoacridine mono-hydrochloride.  In examples: (1) and (2), 2 : 7-dinitroacridone is prepared by reacting fuming nitric acid and concentrated sulphuric acid, or nitric acid and concentrated sulphuric acid with 2-nitroacridone dissolved in concentrated sulphuric acid; (3) 2 : 7-dinitroacridone, prepared as in (2), is reduced to 2 : 7-diaminoacridone with stannous chloride dissolved in concentrated hydrochloric acid; (4) 2 : 7-diaminoacridone, prepared as in (3), is reduced to 2 : 7-dimainoacridane with sodium amalgam and is oxidized to 2 : 7-diaminoacridine with oxygen in the presence of ferric chloride, and is converted to 2 : 7-diaminoacridine monohydrochloride by the addition of hydrochloric acid and salting out with a strong solution of sodium chloride and/or ammonium chloride.
